Inventor: KUNZ CHRISTIAN
IPC: F25J3/04
Filed: 1999-10-29
Granted: 2001-05-01
Abstract: The invention relates to a process for producing ultrapure nitrogen by low-temperature fractionation of air in a rectification system having at least one rectification column, in which process compressed and purified feed air is conducted into a pressure column, an oxygen-free pressurized nitrogen fraction is produced from the pressure column, conducted into a low-pressure column and in the low-pressure column carbon-monoxide-free low-pressure nitrogen is produced as overhead gas. According to the invention, the oxygen-free pressurized nitrogen fraction (1) is either taken off in the liquid state from an upper region of the pressure column or is provided from a liquid tank (22) containing stored oxygen-free nitrogen and the oxygen-free pressurized nitrogen fraction (1) is expanded into the bottom-heated low-pressure column (2).

Title: Phase detector architecture for phase error estimating and zero phase restarting
Inventor: STASZEWSKI ROBERT B
IPC: G11B20/10
Filed: 2000-03-01
Granted: 2003-08-21
Abstract: A system and method for enabling an efficient zero phase restart (ZPR) of a device. The structure is based on deploying normalized timing gradient (NTG) blocks (501 and 502) in pairs, each circuit employing an orthogonal phase error transfer function characteristic (having one TG circuit sample orthogonally in relation to the other), for example, PR4 and EPR4 modes ideal sampling instances of a preamble. Through iteration of the method of the invention, an NTG block (501 or 502) is selected based on having a native timing sampling instance with a phase error that is closest to zero. Since there is an equal chance that either of the circuits in a circuit pair will be selected, if the circuit implementing the current non-native architecture is selected, a separate signal is generated. This signal adds the equivalent of 180 DEG to the error value that is provided to the timing recovery circuit. For example, by iterating the process after the special case of a zero phase restart (ZPR) operation, the native sampling instance is ""forced"" to be selected thereafter.

Title: Exhaust gas catalytic converter
Inventor: LLOYD JONATHAN
IPC: F01N3/28
Filed: 2000-03-09
Granted: 2002-05-21
Abstract: A combustion engine catalytic converter comprises porous mesh sheet material made of metal fibers having a diameter of about 1-30 microns coated with a catalyst and formed into corrugations, the material having a void volume of preferably about 80-95%. Adjacent sheets have corrugations in one example at 45 DEG C in opposite directions relative to the gas inlet and outlet flow directions. The sheets create turbulence creating a pressure drop across the sheet material and causing exhaust gas to flow through the sheet material interstices in contact with the catalyst in the interstices. The material is light weight, has low mass and exhibits good cold start up heating in less than 1 minute. The pressure drop across the converter, with turbulence in the gas flow, is comparable to honeycomb prior art converter structures exhibiting laminar flow, uses less catalyst, is more efficient and is lighter. Various embodiments are shown employing vortex generators for providing turbulence in addition to the zig-zag corrugated channel orientation or to provide tortuous channel paths for the gas flow to create the desired turbulence.

IPC: G10L17/02
Filed: 2000-03-31
Granted: 2001-12-21
Abstract: Methods and apparatus are disclosed for retrieving audio information based on the audio content as well as the identity of the speaker. The results of content and speaker-based audio information retrieval methods are combined to provide references to audio information (and indirectly to video). A query search system retrieves information responsive to a textual query containing a text string (one or more key words), and the identity of a given speaker. An indexing system transcribes and indexes the audio information to create time-stamped content index file(s) and speaker index file(s). An audio retrieval system uses the generated content and speaker indexes to perform query-document matching based on the audio content and the speaker identity. Documents satisfying the user-specified content and speaker constraints are identified by comparing the start and end times of the document segments in both the content and speaker domains. Documents satisfying the user-specified content and speaker constraints are assigned a combined score that can be used in accordance with the present invention to rank-order the identified documents returned to the user, with the best-matched segments at the top of the list.
